Extensive application data of stainless steel joints in pipeline construction:
Stainless steel pipe is a kind of pipe fittings, stainless steel material is it made so called stainless steel pipe fittings, stainless steel pipe fittings which include: stainless steel elbow, stainless steel tee, Eaton cross rust steel welded joint, stainless steel reducer, stainless steel pipe cap, etc., according to join method can be divided into the socket type stainless steel pipe fittings, flanges threaded stainless steel pipe fittings, stainless steel pipe and welded stainless steel pipe fittings four classes.Where the stainless steel elbow is used for turning the pipe fitting;Xi 'an spray nozzle universal joint flange is used for connecting the pipe to the pipe parts, connected to the end of the pipe, stainless steel tee pipe is used for three pipe collection place;A stainless steel four-way pipe is used where four pipes meet;Stainless steel reducing pipe is used for connecting two pipes of different diameters.
Stainless steel pipe fittings are all kinds of stainless steel pipeline connection workpiece, can be divided into different categories according to shape, purpose, jiangsu stainless steel straight joint connection way.It has the characteristics of easy installation, high performance and durability, and is widely used in the construction and installation of various pipelines.
Stainless steel pipe fittings can be divided into stainless steel tee, stainless steel flange, stainless steel size head guangdong stainless steel tee joint, stainless steel elbow, stainless steel pipe cap, stainless steel seal head.
Stainless steel pipe fittings three dimensional finite element model is established, through the stress analysis found that under the condition of axial compression coil pipe compression face obvious stress concentration phenomenon, the compression of forecasting fitting end edge effect to cause a decline in tube axial compressive strength, by three-dimensional finite element model for end enhance and strengthen the control of axial compression strength separately carried on the quantitative calculation, have to Eaton flaring type joint axial compression strength of the end strengthen the fitting was obviously higher than that of strengthening the control of axial compression strength.
The thrust support of space carrier refers to the main bearing structure on the carrier that transfers the large thrust generated by the engine from one structure to another. It is generally composed of stainless steel pipe fittings, stainless steel joints, end frames and end plates.Stainless steel pipe fitting is the main part of thrust support with large load.The results show that the negative influence of the end surface effect on the axial compression strength can be effectively reduced and the axial compression strength can be increased by more than 30%.
Stainless steel pipe fittings are not easy to produce eton carabiner joint rust and stainless steel composition has a great relationship.
Stainless steel in addition to iron, there are chromium, nickel, aluminum, silicon and so on.General stainless steel chromium content is generally not less than 12%, high even up to 18%.
When chromium and other elements are added into the steel, the performance of the steel can be changed. For example, the molecular structure of the steel is more uniform, and it is easier to form a dense oxide protective film on the surface of the steel, so as to greatly improve the corrosion resistance of stainless steel.
So stainless steel can resist fire, water, acid, alkali and a variety of solutions to its corrosion, not rust.
